WEB SLITTING AND WINDING APPARATUS.

SPIECFICATION forming part of Letters Patent No. 674,919, dated May 28, 1901. Application filed March 7, 1901. Serial No. 50,181. KNO model.)

To all whom, it nay concern:

Be it known that I, JOHN PARKER JEF- FERIs, a citizen of the United States, residing at VVilmingtomcounty of Newcastle,and State of Delaware, have invented certain new and useful Improvements -in a Combined Web Slitting and Winding Apparatus, fully described and represented in the following specification and the accompanying drawings, forming a part of the same.

This invention relates to combined web slitting and winding apparatus-that is to say, apparatus in which a main web is slit longitudinally into a number of webs, which are then guided onward side by side to a winding mechanism, where the several webs are by frictional contact with a suitably-driven winding drum or drums wound side by side into a like number of rolls upon a core which is common to the several rolls and which is removable, so that when the winding operation is completed it may be withdrawn from the rolls wound upon it and reused in the winding of other webs.

In combined web slitting and winding apparatus as heretofore constructed the webs as they travel onward side by side from the slitting mechanism to the winding mechanism have a tendency to approach each other and to overlap at their adjacent edges, s'o that the several rolls formed from the webs instead of being disconnected,as they should be, have their ends connected to the extent to which the webs so overlap. This prevents the formation of perfect rolls, as the overlapping of the edges of the webs produces wrinkles, causes each roll to be loose or soft and of unequal diameter, (the roll being larger at its ends than between them,) and, moreover, renders it necessary in order to separate the rolls upon withdrawal of the core for the workman to forcibly pull the several rolls apart.

It is the object of the present invention to overcome these difficulties and to provide a novel form of web-spreading device for engaging the webs as they travel onward from the slitting mechanism in such way as to spread them apart, and thus overcome this tendency to approach each other, so that the webs upon reaching the winding mechanism will be wound into rolls disconnected from each other and without any overlapping of their adjacent edges, the means provided for this purpose by the present invention being adjustable, so as to spread apart not only two such webs, but any number of webs into which a main web is slit as it travels onward to the winding mechanism.

The improvements of the present invention have been designed particularly for use in apparatus for operating upon webs of paper, in which apparatus they have peculiar advantages, and they will therefore and for convenience be described in connection with suoli apparatus.

In the accompanying drawings, Figure l is a side elevation of a combined web slitting and winding apparatus embodying the presentinvention,illustrating also means for guiding the main web to the slitting mechanism and for guiding the slit webs from the latter to the winding mechanism. Fig. 2 is a front view, looking toward the left of Fig. l, of the means for guiding the slit webs from the slitting mechanism to the winding mechanism, illustrating also the spreading device provided by the present invention for engaging the slit webs and spreading them apart, the number of webs shown as so -spread apart in this view being two. Fig. 3 is a section on the line 3 3 of Fig. 2, illustrating particularly the manner in which the spreading device engages the surfaces of the slit webs to spread them apart. Fig. L is a section, on au enlarged scale, ou the line 4 L of Fig. 3. Fig. 5 is a section on the line 5 of Fig. l; and Figs. 6, 7, 8, and 9 are edge views of the spreading device adjusted or bent into position to spread apart five, four, three, and six webs, respectively.

Referring to said drawings, 1 2 represent a pair of web-guiding rolls for guiding a main web W of paper from the usual unwinding mechanism (not shown) or other source of supply toward the slitting mechanism of the apparatus, consisting in the case shown of upper and lower slitters 3 l,while 5 represents a web-guiding board or plate interposed between the roll 2 and said slitting mechanism for guiding and supporting the web from the former to the latter. The upper slitter 3, which is driven by frictioual engagement with lower slitter Il, is journaled in au arm 6, adjustably secured to a shaft 7 in frame A by a IOO set-screw 8, so that the sl'itter 3 may be adjusted longitudinally of said shaft and to and from lower slitter 4 or swung into or out of operative relation to said slitter 4. The lower slitter 4 is also adj ustably secured to a suitably-driven shaft 4*, so that it 'may be adj'usted longitudinally thereof. Only one pair of such slitters is shown; but it will of course be understood that as required others may be added or removed according as the main web W is to be slit into a greater or a less number The Vmain web W in passing 1 667,893, and vincent Hazard, No. 667,879. Briefly described, it consists of a pair of suitably-'driven winding-drums 11 12, which by j frictio'nal'e'ngagemen't with the 'minor'webs w said patents. upon the core 13 and'the rolls 'of material on the latter are thus 'increased in diameter the aforesaid patents, its upward movement being device (not shown) connected to Aand opera ted 'b'y 'a sprocket-chain 14, which is in turn Voperated by the'core 13 as 'it moves upwardly through connections consisting of a llever 15, pi'voted in the hi'nged mem berl of the bracket in which the core 13 is journ'aled and'engaging a'cat'ch 17 upon a bracket 13, secured to the sprocket-chain 14 and mounted so as to 'slide and operation ofthi's winding'ineohan'ism reference is vhereby in 'ade tothe aforesaid patents. f As before stated, the slit webs after'leaving 1,

The means shown consists of a spreading-. bar 20, mounted upon a shaft. 21, and which i'nuse is bowed or bent out' of parallelism with will be wound upon the core 13 without anyT overlapping of their adjacent edges and with the several rolls upon the core disconnected from each other and each roll wound uniformly widthwise and'free from wrinkles.

In Figs. 1 to 3 a single pair of slitters 3 4is shown located centrally of the main web W, so that the main web is severed into onlytwo minor webs w, and the spreading-bar of these figures therefore has but a single curved or high part for engaging and spreading apart the two webs, this curved or high part being located in line with the adjacent edges of the webs. In combined web slitting and winding machines, however, the number of minor webs into which a main web is slit varies, the main web being sometimes slit by the employment of vadditional slitters 3 4 into three, four, or even a greater number of vvebs. 4The spreading-bar 2O of this Aapplication is thereforedesigned 'to operate not only 'upon two webs, as show-n in Figs. 1 to 3, but u'pon such additional webs, Vand v.for this reason it 'is made of ilexible material, so 'that it 'may be readily adj usted or bent into any desired number of curves, and is also provided with devices for l so adjusting or bending it, which devices will as they are wound upon a 'removable core 13 rotate said core, vand thus wind the webs fw i thereon, as 'more fully described inthe aforeg As the'webs w `are 'thus wound now be described. Each of the adjusting devices referred to (of which there 'maybeany number, Vaccording to the number of `slit 'webs to be operated upo'n andthe number ofcurves to Vbe formed 'in the bar 20) consists ofa s ufpport or clamp 22, in which the 'spreading-bar core 13 "moves upwardly, as described 'in the 1 is mounted, a screw-'threaded spindle 23 free g to tu'rn in said clamp, and abrack'et 24, v(see at iirst resisted and'then assisted, so as to secure properwinding of thewebs, lbyapressure f' Fig. 4,) mounted Vupon shaft 21 and provided with a threaded opening for receiving 'the threaded end of the spindle. Each of the clamps 22 is connected to the spreading-'bar 2O in such way as to permit movement of each relatively to l`the other vlongitudin''ally of the shaft 21, 'and the brackets v24 'are likewise movable longitudinally of said shaft,so that the clamp 22 rnay'ibe adjusted to any'desired position along the spreading-'bar 20. Each vertically upon a guide 19 on 'the frame B. 'For Va fuller description of the construction f of thebrackets 24 is provided with a vset-screw 25,b'y`which it' maybe secured vtotheshaft'21 in 'its adjusted positions, vand each of the spindles 23 is also provided 'with a handle 26 for convenience in vturning it. By means 'of E these adjusting devices the spreading-bar 2O 'the winding mechanism have a tendency to i may :be 'bent or adjusted into any desired For `exam ple, to bend or 'adj ust the spreading-bar 20 to operate upon two webs, asin Figs. 1to 3, the Yseveral spinsurfaces of the 'webs as they travel onward@ dles VV23 will be rotated,'so that the spreadingbar 2O will be vbent into 'a'single curve, with 'mechanism 1n such way as 'to spread 'their-g the middle or high part of the bar in line with Forthree webs the-spreading-bar 2O will be bent by the adjusting devices into the form shown in Fig.

in Fig. S-that is to say, for two and three webs-but for bending the bar 2O into the forms shown in Figs. 6, 7, and 9 additional adjusting devices will of course be employed, the number of adjusting devices employed and their positions along shaft 2l varying as the form of the spreading-bar is varied. In addition to this adjustment or bending outwardly relatively to its supporting-shaft 2l the spreading-bar 2O is adapted for lateral adjustment bodily into and out ot' the path of movement of the webs 1U, the supportingshaft 21 for this purpose being mounted at its opposite ends in arms 27, to which itis secured by set-screws 2S, the upper ends of said arms being secured by set-screws 29 to pins 30, fixed by means of set-screws 3l in the frame A. By loosening the set-screws 29 and 3l the arms 27 may be swung inwardly or outwardly relatively to the path of movement of the webs, so as to cause the spreadingbar 2O to project to a greater or less extent into the path of movement of the webs w or to move said spreading-bar out of operative position relatively to said webs.
